Description

A Shihu principle demonstration device with a model organism having a wind-driven structure

technical field

The invention relates to the field of demonstration model design, in particular to a Shihu principle demonstration device with a model organism having a wind-driven structure.

Background technique

Shihu is a fishing method in Penghu where people and the sea are interdependent, and it is also a fishing fortification. The principle is to use the tidal rise and fall to pile up two long arc-shaped embankments in the intertidal zone, extending from the shallow water to the deep water, and using the height difference between the shallow water embankment and the deep water embankment to make a hook shape at the end of the deep water . When the tide is high, fish schools follow the seawater into the stone lake to feed on seaweed; after the tide ebbs, the shallow water embankment and the deep water embankment are successively higher than the sea surface, and the fish swim back to the curling place and are blocked and trapped in the lake. Fishermen use this to catch fish. The simple structure of Shihu makes use of natural principles such as tides and ocean currents, which fully embodies the wisdom of the people in ancient times.

The first document of Shihu in Penghu, Taiwan was recorded in the Taiwan County Annals in 1720 AD, which fully embodies the wisdom of the ancients. However, with the advancement of the times and the rapid development of science and technology, fishing equipment and fishing methods have developed by leaps and bounds, and the fishing efficiency of modern fisheries far exceeds that of ancient fishing methods. As a result, the crystallization of the wisdom of ancient people such as Shi Hu was gradually forgotten. The existing stone lakes are mainly used as tourist attractions for tourists to visit, such as the famous "Twin Heart Stone Lake" in Penghu, Taiwan.

The Shihu principle demonstration device is a device that demonstrates the Shihu principle based on the Shihu model. It simulates natural phenomena such as tides and ocean currents, and can clearly demonstrate the functions of Shihu. It is often used as a teaching demonstration to enable students to understand traditional culture and technology, and learn natural science.

In order to simulate the process of fishing with rockfish, model organisms are bound to be added to simulate sea fish or marine life in the existing stonefish principle demonstration device. The existing stonefish principle demonstration device usually uses water flow to control the flow direction of model organisms, but In the process of water injection, the water flow is usually relatively turbulent, and errors are prone to occur in the control of the flow direction of the model organisms. If the model organisms cannot accurately enter the fishing area of Shihu, the demonstration process of the existing Shihu principle demonstration device will fail. of.

It can be seen from the above that by applying the technical solution of this embodiment, when in use, the first pipe is used as the outlet pipe to fill the box with water, and the model organisms float close to the water surface. Since the first pipe outlet makes the water flow direction point to the model deep-water embankment, this When the current simulates the ocean current, the model creature slides to the position of the model shallow water embankment and the model deep water embankment. At this time, the first pipeline stops entering the water, and the water flows away from the hole between the model shallow water embankment and the model deep water embankment at the bottom of the Shihu model. The decline simulates the tide, and the model organisms are left between the model shallow water embankment and the model deep water embankment, completely simulating the principle of Shihu, and clearly demonstrating the function of Shihu, which is convenient for teaching demonstrations, so that students can understand traditional culture and technology , study natural science. On this basis, in order to precisely control the direction of the model organisms, a pneumatic device is installed on the box opposite to the shallow water bank of the model. Blowing in the direction of the shallow water embankment, at this time, the airflow will drive the water flow towards the model shallow water embankment, then the model organisms floating under the water will follow the direction of the water flow, and flow in the direction of the model shallow water embankment, thus making the direction of the model organisms A clear pointing is provided to ensure the correct displacement of the model organism.

This embodiment utilizes the reset function of Embodiment 4 in actual use, and the first pipe 120 can make the water in the water storage tank 130 be utilized, so that this embodiment can be used independently and recirculated without an external water source.

Its use process is as follows. A certain amount of water is stored in the water storage tank in advance. When in use, the first water pump 121 is turned on, and the first water pump 121 pumps the water in the water storage tank 130 into the tank 100. As the water level of the tank 100 rises, The model organism 101 floats with the water surface, and at this time, while the water level is rising, the water outlet of the first pipeline 120 can provide water pressure due to the first water pump 121, and the water pressure generates water flow, which points to the model shallow water embankment, and the water flow simultaneously drives The model organism 101 flows to the position of the model submerged embankment and the model deep water embankment.
